Foam Roller: A foam roller is a cylindrical piece of dense foam used for self-myofascial release (SMR), a technique designed to release muscle tightness, improve flexibility, and enhance circulation. It is commonly used in physical therapy, athletic training, and fitness routines. Foam rolling helps relieve muscle soreness, reduces muscle tension, and can aid in faster recovery after exercise. It works by applying pressure to specific areas of the body, encouraging muscles to relax and release knots or trigger points. Foam rollers come in various densities, sizes, and textures, catering to different needs and comfort levels.
